Anti-Bot Checker

Check what anti-bot, WAF, CAPTCHA, and other protection systems a website uses See the difficulty verdict and the exact cookie, header, or script behind each detection

Bot protection detection
Evidence-based results
IP behavior comparison

Site to check

One ordinary request from our datacenter IP, the same as opening the page in a browser.

We never send attack traffic and never try to bypass anything we find.

Understand what the scan found

The Anti-Bot Checker gives you more than a list of protection systems. See how difficult the site appears to access, what was detected, and the evidence behind each finding

Difficulty verdict

01

See the overall result: No barrier observed, Easy, Moderate, Hard, or Very hard. The verdict can be inferred from the systems found or measured through an IP comparison

Protection details

02

See what each detected system means for access, including whether plain HTTP works, JavaScript is required, and IP reputation matters

Evidence

03

Open the finding to see the exact cookie, header, or script that led to the detection

Checked systems

04

See which known protection systems were checked but not observed, so an empty result isn't mistaken for proof that the site is unprotected

The checker doesn't just give you a vendor name

Cookies
Identify cookies associated with the detected system
HTTP headers
See relevant response headers used by the detection
JavaScript
Find protection signals that only appear when page scripts execute

Check 21 known protection systems

The Anti-Bot Checker covers several types of website protection

* We document these four but have not yet confirmed them against a response we recorded ourselves, so a scan will not report them.

Bot management

DataDome · F5 BIG-IP ASM / Shape · HUMAN Security (PerimeterX) · Kasada · Amazon in-house * · Reblaze *

WAF

AWS WAF · Imperva · Sucuri

CAPTCHA

Arkose Labs (FunCaptcha) · Cloudflare Turnstile · GeeTest · Google reCAPTCHA · hCaptcha

CDN

Akamai · Amazon CloudFront · Cloudflare · Fastly

Fingerprinting

Browser fingerprinting · LexisNexis ThreatMetrix *

Why use an Anti-Bot Checker?

Use case
How it helps
Before scraping
See what protection a target uses before building a scraping workflow
Before automation
Understand whether the site relies on bot management, WAF rules, JavaScript, or other signals
When requests behave differently
Use detection results and evidence to investigate unexpected responses
When testing proxy types
Compare datacenter and residential responses to see whether IP type affects the target

Frequently asked questions

An anti-bot checker identifies technologies that websites use to detect or manage automated traffic, including bot-management systems, WAFs, CAPTCHAs, and other protection signals.

It starts with one ordinary GET request. If no known protection is identified, it automatically re-checks the page in a real browser to detect systems that only become visible after JavaScript runs.

Some protection systems don't leave an identifiable signal in a basic HTTP response. That's why the tool can perform an automatic browser re-check.

A clean result means no known system was identified in this scan. It does not prove that the website has no protection.

A CDN handles content delivery and traffic routing. A WAF filters traffic according to security rules. Bot-management systems evaluate traffic for signs of automation.

A CDN such as Cloudflare does not automatically mean that a website is using bot protection.

It can detect Cloudflare and Cloudflare Turnstile when the relevant signals are observed.

The presence of Cloudflare as a CDN alone is not treated as proof of bot protection.

Yes. DataDome is one of the bot-management systems in the current detection set.

Yes. The checker includes HUMAN Security (PerimeterX) among its bot-management detections.

Websites can use IP reputation as one of the signals when evaluating traffic. Compare IPs lets you measure whether the same URL produces different responses from datacenter and residential IPs.

No. It identifies and measures observed protection. It does not attempt to bypass or defeat it.
